The King and Queen have both seen an enormous rise in their popularity ever since His Majesty acceded to the throne and took on the job he had waited his entire life for.
The couple have been married for 18 years and have worked incredibly hard to prepare for their leading roles ever since.
One of the greatest binds between the couple is their shared sense of humour, with royal expert Jennie Bond explaining that they enjoy "Nothing more than a belly laugh together."
Speaking exclusively to OK!, Jennie said: "One of the greatest gifts in a long relationship is humour and it is something that Charles and Camilla have shared from the start.
"She understood his love of the comedy show The Goons and completely understood his wacky, quiet, school boyish sense of humour.
"Diana was a giggler too… but in the end she tended to giggle AT Charles, rather than with him."
Jennie adds that The Queen is also skilled at calming The King down whenever necessary. “I think it's always one of her great strengths. She just knows how to deal with him.
"When he is in one of his moods, her approach is very much to just stand back, let him explode and then just carry on smoothly."
“Camilla is terribly good at pouring oil on troubled water. She is probably the one person who would dare to – and can – talk to him when he's feeling cross, and he's unlikely to shout back at her.”
Perhaps one of the couple's best loved moments came in 2017 when they undertook a three-day tour of Canada.
They were treated to a traditional performance by Inuit throat singers during an official welcome ceremony at Nunavut Legislative Assembly in Iqaluit, Canada. They were both left close to tears as they giggled during the performance.
The Inuit Culture Online Resource explains: "Throat singing was traditionally performed between two women. The songs are sung as a friendly competition; played as a game.
"One person sets the rhythm, the pace the sound and the other follow. The first person to outlast or not laugh is the winner, as each song tends to end in laughter."
